Netscape says "Document Contains No Data"

Using Oracle WebServer Java Cartridge

Using JavaCacheTimeout = 0

I am selecting a table of 14 columns by 110 rows into an
Oracle.html table.  I can display this once.  If I click
on the reload button, I get a Netscape panel that says
"Document Contains No Data."  If I wait 10 or 15 minutes
before I click "Reload," I can re-display the table.

HELP!!!!!

Code follows:

import oracle.html.*;
import java.util.*;
import java.io.*;
import java.lang.*;
import oracle.owas.wrb.services.http.*;
// You need to import the java.sql package to use JDBC
import java.sql.*;
// You need to import oacle.jdbc.driver in order to use the oracle exten
sions.
import oracle.jdbc.driver.*;
